kick his own ass?
He'd have to move his head out of the way first.
“kick his own ass?”
The ass getting kicked this November is the donkey known as the Democrat Party and Barack Obama is a principal (though not exclusive) reason for this. So even though his verbal posturing is likely just an idle threat, he in fact will be delivering a serious ass-kicking to his own party this fall, which is why growing numbers of party members are abandoning his leaky ship. Like LBJ, he is going to have to abandon all hope of being re-nominated for a second term.
